The Bosch LH1-UC30E Music Horn Loudspeaker
features a two‑way system, resulting in an extended
frequency range and high sensitivity which makes it
ideal for high quality speech and music reproduction.

Functions

The rectangular horn features a unique combination of
a re‑entrant horn with two transducers, one for low–
and the other for high frequencies, resulting in
breathtaking sound clarity.
The horn is weather protected and can be used in
areas with high humidity. It is therefore suitable for
outdoor applications such as sport grounds, sports
stadiums, leisure parks, exhibition areas and
passenger terminals, as well as for indoor public
address.
The ABS horn loudspeaker and aluminum bracket are
finished in light grey (RAL 7035).
The LH1‑UC30E is designed for use in voice alarm
systems and is EN 54‑24 certified and compliant with
BS 5839‑8 and EN 60849.
The horn loudspeaker has built‑in protection to ensure
that, in the event of a fire, damage to the loudspeaker
does not result in failure of the circuit to which it is
connected. In this way, system integrity is maintained,
ensuring loudspeakers in other areas can still be used

u EN 54‑24 certified

to inform people of the situation. The horn
loudspeaker has ceramic terminal blocks, thermal fuse
and heat resistant high temperature wiring.

Certifications and approvals

All Bosch loudspeakers are designed to withstand
operating at their rated power for 100 hours in
accordance with IEC 268-5 Power Handling Capacity
(PHC) standards. Bosch has also developed the
Simulated Acoustical Feedback Exposure (SAFE) test
to demonstrate that they can withstand two times
their rated power for short durations. This ensures
extra reliability under extreme conditions, leading to
higher customer satisfaction, longer operating life, and
much less chance of failure or performance
deterioration.
